Principle and conditions


In accordance with Article 1 of the tax treaty between France and Monaco of 18 May 1963 corporate income tax was introduced in the Principality by the  Ordinance no. 3.152 of 19 March 1964 instituting a profit tax .

The following entities are subject to this tax:

  • Companies of any legal status that carry out industrial or commercial activity, where at least 25% of the turnover is generated outside Monaco
  • Companies whose income relates to the sale or licensing of patents, trademarks, processes or formulas and to the royalties from intellectual property rights

Administrative offices are also subject to this tax but it  is applied  according to the specific terms relevant to their situation. The tax is determined by a flat rate, generally equal to 8% of the total annual operating expenses.

How taxable profit is calculated

Taxable profit is calculated according to the profits derived from activities of any nature carried out by the company. It is determined after deduction of all costs. However, specific rules mean that the salary of the owner or directors can only be deducted for individuals who carry out a real function within the company and at a total value that is reasonable for their role.

For small businesses (defined as companies with a turnover of less than €3.5 million for the provision of services or €7 million for other activities) a scale determines the maximum amount of deductible income per turnover bracket. For other companies the director’s salary can only be deducted from taxable profits if the amount is not excessive in comparison to recognised practices on an international level, particularly within the European Union.

Rate of taxation

The rate of taxation is:

  • 33.33% for financial years commencing before 1 January 2019
  • 31% for financial years commencing on or after 1 January 2019
  • 28% for financial years commencing on or after 1 January 2020
  • 26,5% for financial years commencing on or after 1 January 2021
